Substitute Part Grouping Explanation

Substitution eligibility for the EET-HC2W221DA is determined by strict equivalence across the following parameters:

Capacitance: 220 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.394" (10.00mm) (exact match required)
Diameter: 1.181" (30.00mm) (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in height, ESR, ripple current ratings, and lifetime specifications do not disqualify substitution but indicate performance differences suitable for specific application requirements.

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing status, providing supply continuity for the obsolete EET-HC2W221DA. Selection between substitutes should be based on the following criteria:

Rubycon 450MXK220MEFC30X25: Offers compact height (27.00mm) with extended 3000-hour lifetime. Suitable for space-constrained applications where the reduced height does not conflict with board layout requirements.

Rubycon 450VXG220MEFCSN30X30 and 450VXH220MEFCSN30X30: Both provide extended 5000-hour lifetime at 105°C with identical mechanical dimensions matching the original part. The 450VXH220MEFCSN30X30 carries ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), matching the original part's environmental specifications.

EPCOS B43508 Series (all variants): Multiple part numbers within the B43508 series provide 3000-hour lifetime with identical mechanical dimensions. All variants carry ROHS3 compliance and unlimited moisture sensitivity rating. The B43508C5227M80 variant shows a marginal height tolerance of 1.268" (32.20mm), within acceptable mechanical substitution limits.

All substitute parts are REACH-compliant and classified under ECCN EAR99 with matching HTSUS code 8532.22.0040.

Frequently Asked Questions (FAQ)

Q: Can the 450MXK220MEFC30X25 be used as a direct replacement despite its reduced height?

A: The 450MXK220MEFC30X25 meets all electrical and core mechanical parameters (capacitance, voltage, tolerance, package type, lead spacing, and diameter). The reduced height of 27.00mm versus 32.00mm requires verification that board layout and component clearances accommodate the shorter profile. No electrical incompatibility exists.

Q: What is the difference between the Rubycon VXG and VXH series substitutes?

A: Both 450VXG220MEFCSN30X30 and 450VXH220MEFCSN30X30 share identical electrical ratings (220 µF, 450 V, 5000-hour lifetime) and mechanical dimensions. The primary distinction is moisture sensitivity level: VXH carries MSL 1 (Unlimited), matching the original EET-HC2W221DA specification, while VXG does not specify MSL rating.

Q: Are all EPCOS B43508 variants electrically equivalent?

A: All B43508 variants listed (M000, M062, M2, M60, M67, M7, M80) share identical electrical specifications: 220 µF capacitance, 450 V rating, ±20% tolerance, 560 mOhm ESR @ 100Hz, and 3000-hour lifetime at 105°C. Variants represent different manufacturing codes or packaging configurations with no functional electrical differences.

Q: Does the extended lifetime of substitute parts affect circuit design?

A: Lifetime specifications indicate component reliability duration under rated conditions. Extended lifetime (3000 or 5000 hours versus 2000 hours) provides improved reliability margins but does not alter electrical performance or circuit behavior. Design parameters remain unchanged.

Q: Are all substitutes RoHS3 compliant?

A: All active substitute parts listed carry RoHS3 compliance certification. The original EET-HC2W221DA is obsolete and does not carry RoHS3 status. Substitution with RoHS3-compliant parts aligns with current environmental and regulatory requirements.
